South African mining investment company Mantengu announced on Friday that Chief Executive and Executive Director Mike Miller had resigned, effective February 28, 2026.
Magen Naidoo, currently Deputy Chief Executive and Chief Financial Officer, will assume the role of CEO starting March 1, 2026.
“Magen has been actively involved in operations as deputy CEO over the past few months, as well as the company’s various acquisitions and group strategy over the past few years,” the company said in a statement.
Mantengu noted that Miller intends to dedicate more time to his family. In recent months, he had spoken publicly about alleged threats to his life following claims of manipulation of Mantengu’s share price.
Naidoo, a former audit partner at Deloitte with over 17 years of experience at the firm, is a chartered accountant with more than 25 years in the industry. He now leads Mantengu as the company continues to expand its operations.
The company’s flagship project is the Langpan chrome and platinum group metals mine, which holds an ore reserve of 2.17 million tonnes. Mantengu has begun refurbishing the plant associated with the project to increase processing capacity to approximately 30,000 tonnes of ore per month (50 tonnes per hour), up from an initial 30 tonnes per hour.
